一种交流特高压直线角钢塔地线支架节点结构
摘要：
本实用新型公开了一种交流特高压直线角钢塔地线支架节点结构，采用节点板和火曲板共同将第一角钢至第六角钢和主材角钢之间相互连接。第二角钢的第一肢采用通过节点板与主材角钢的一肢螺栓连接；另外，第二角钢的第二肢与火曲板连接，且火曲板与第五角钢、第六角钢均螺栓连接，增加了地线支架节点的角钢之间的紧密度，提高了地线支架节点的刚度，有利于地线支架的抗弯、扭作用。并且，第五角钢的第一肢延伸入主材角钢的第二肢内部，同时与主材角钢的第二肢、节点板的第二连接板和第四角钢的第一肢螺栓连接，避免了第五角钢与主材角钢之间的负头过大而不利于轴力的传递的情况。
摘要（英）：

The utility model discloses an alternating current extra-high voltage straight line steel angle tower ground wire support node structure. A first steel angle to a sixth steel angle and a principal material steel angle are connected mutually by adopting node plates and fire bending plates. A first part of the second steel angle is in bolted connection with one part of the principal material steel angle, a second part of the second steel angle is connected to the fire bending plates, the fire bending plates are in bolted connection with both the fifth steel angle and the sixth steel angle, tightness among the steel angles of ground wire support nodes is increased, the rigidity of the ground wire support nodes is improved, and the bending resisting and torque resisting functions of the ground wire support nodes are facilitated. In addition, a first part of the fifth steel angle stretches into a second part of the principle steel angle, and is in bolted connection with the second part of the principle steel angle, second connecting plates of the node plates and a first part of the fourth steel angle, and the situation that the negative margin between the fifth steel angle and the principal steel angle is oversize and is adverse to transmission of shaft force is avoided.
